Four male and three female parents, their twelve hybrids along with three standard checks of rice (Oryza sativa L.) were evaluated during Kharif 2016 to study the nature and extent of correlation among yield and yield attributing characters viz., days to 50 per cent flowering, days to maturity, productive tillers plant-1, plant height (cm), panicle length (cm), total spikelets panicle-1, fertile spikelets panicle-1, spikelet fertility (%), 1000 grain weight (g), grain yield plant-1 (g), straw yield plant-1 (g) and harvest index (%). The results revealed that grain yield plant-1 to be positively and significantly associated with days to 50 per cent flowering (0.988), days to maturity (0.998), productive tillers plant-1 (0.849), panicle length (0.978), total spikelets panicle-1 (0.806), fertile spikelets panicle-1 (0.979) and straw yield plant-1 (0.719) indicating importance of these traits as selection criteria in yield improvement programmes.
